Mantle melting and heterogeneity along mid-ocean ridges : insight from basalt geochemistry along axial depth and morphologic gradients for intermediate spreading rate systems

Creator:: Russo, Christopher J.
Abstract:: This investigation focuses on gaining a better understanding of the complex relationship between melt generation, source variability and mid-ocean ridge morphology. The approach adopted here uses a variety of geochemical techniques to evaluate the ability of 'global' models to predict regional scale geochemical variability associated with axial depth and axial...

Magmatic processes beneath mid-ocean ridges : insights from mineral and glass chemistry in plagioclase ultraphyric basalts

Creator:: Lange, Amy E.
Abstract:: Prior to eruption at mid-ocean ridges, melts must travel through >6 km of crust from their origin in the mantle. The final composition of the melts is dependent on both the melting conditions and magmatic processes within the crust. While mid-ocean ridge basalt (MORB) glasses are commonly used to infer...

Geochemistry of mid-ocean ridge basalt within and surrounding the Australian-Antarctic discordance

Creator:: Pyle, Douglas G.

Full Text:: between isotopically distinct Indian and Pacific mid-ocean ridge basalt (MORB) occurs beneath the AAD

Magmatic processes at mid-ocean ridges : evidence from lavas and melt inclusions from the Southeast Indian Ridge, the Endeavour Segment of the Juan de Fuca Ridge, and the northern East Pacific Rise

Creator:: Sours-Page, Rachel E.
Abstract:: Magmatic processes control the chemical compositions of all lavas erupted at mid-ocean ridges. In this thesis, I present studies of magmatic processes on three different mid-ocean ridges to determine which processes are in action and to what extent each has affected the chemistry of mid-ocean ridge basalts at each location....

Crustal structure and seismicity of the Gorda Ridge

Creator:: Solano-Borrego, Ariel E.
Abstract:: We have determined the seismic crustal structure of the northern part of the Gorda Ridge using signals generated by explosive charges and recorded on Ocean Bottom Seismometers. The shot pattern forms two parallel lines, one on the east flank and the other along the median valley. Inversion of the travel...

Evolution of Turbulence, Heat Content, and Freshwater Lenses in the Diurnal Warm Layer

Creator:: Moulin, Aurélie J.
Abstract:: Thorough understanding of the mechanisms controlling the temperature structure in the surface mixed layer of the ocean and, in particular, accurate values of sea surface temperature are critical for properly parameterizing air-sea heat exchange and quantifying the amount of heat redistributed below the surface. It is however difficult to obtain...

Prokaryotes associated with marine crust

Creator:: Mason, Olivia Underwood
Abstract:: Oceanic crust covers nearly 70% of the Earth's surface, of which, the upper, sediment layer is estimated to harbor substantial microbial biomass. Marine crust; however, extends several kilometers beyond this surficial layer, and includes the basalt and gabbro layers. In particular, the basalt layer has high permeabilities which allows for...

Modeled Larval Connectivity Patterns in two Coral Reef Regions : the Western Caribbean and the Kenyan-Tanzanian Shelf

Creator:: Mayorga Adame, Claudia Gabriela
Abstract:: Tropical coral reef ecosystems are very important from both the ecological and economical points of view. However, they are also particularly fragile, and have been declining in recent years in most regions of the world, since they are highly susceptible to anthropogenic stressors operating at global scales (e.g., global warming...

The 2004 Indian Ocean tsunami : tourism impacts and recovery progress in Thailand’s marine national parks

Creator:: Meprasert, Somrudee
Abstract:: The 2004 Indian Ocean tsunami raised concern among marine park managers and hazard mitigation professionals about the significant impact of major coastal hazards on marine park natural resources and ecosystems. The main reason for this concern is the strong linkage of marine parks and their rich assortment of ecosystem services...
